Megyn Kelly and NBC are still scrambling to finish the third episode of the NBC host's Sunday news magazine, which this week features an interview with Alex Jones.

The program appeared to be in good shape last Sunday when the network aired its first preview, but things soon took a turn when that one-minute segment was met with outrage among many.

No one was more upset however than the family members and friends of the 20 students and six educators killed at Sandy Hook Elementary School in a 2012 massacre that Jones has called a hoax in the past.

Some took to social media to lash out at Kelly and she was fired from her post as host of the charity's annual gala, a move that also left her without content to run on Sunday as she planned to film the event for her show.

The network and Kelly managed to kill two birds with one stone it seems however, with Page Six reporting that Kelly has invited the parents of some victims of the Newtown, Connecticut shooting on the show and interviewed them to balnce out the segment.

Other parents however are still appalled, and in a legal letter to NBC, 12 family members asked that the network not air the program over threat of a lawsuit.

It is unclear on what grounds they might sue and it is not revealed in the letter, which was sent to NBC counsel Kimberley D. Harris, NBC News chairman Andy Lack and Kelly's executive producer David Corvo.

'NBC was scrambling to find a way out of this mess without having to back down and cancel Sunday’s episode of Megyn’s show,' a source told Page Six.

'Megyn and her producers made numerous calls to the Sandy Hook families this week to ask them to appear on the show. Some refused because they didn’t think appearing on her show would do enough to counter Alex Jones’ venom.'

Another source added that 'everyone on the show believes it’s vitally important that the piece conveys the immense pain that Jones has caused the Sandy Hook families.'

Neil Heslin, the father of 6-year-old victim Jesse Lewis, is among those who will be making an appearance on the program.

Meanwhile, 12 of the parents refused to sit down with Kelly and instead fired off a legal letter threatening to sue the network if they aired the interview on Sunday.

'Surely, we can agree that these families have suffered enough already, and that they will continue to suffer enough to last several lifetimes,' resds the letter, penned by attorney Joshua Koskoff.

'Which is why we cannot fathom – from a moral, ethical or legal standpoint – NBC’s decision to amplify the voice of a man who has made a living debasing that suffering and smearing our clients’ names.'

Then letter then goes on to address Jones, and the pain he has caused the already grieving parents of these children.

'Over the last few years, Alex Jones has weaponized his radio show to publish false and defamatory statements about our clients: chief among them that they are actors perpetrating a massive fraud on the American public by faking the deaths of their loved ones,' states the letter.

'Parents have marked their children’s seventh, eighth, and ninth birthdays not with wonder and joyful chaos, but with the most profound loneliness this world knows,' reads the letter.

'NBC is not responsible for the harassment and abuse Alex Jones has cruelly visited on our clients.'

It continues: 'But, by choosing to air his interview with Ms. Kelly – at all, let alone at prime time on Father’s Day – NBC has tendered its good name and considerable influence to provide Mr. Jones with something he has never enjoyed: legitimacy.

'This decision may be driven by the simple urge to gain an edge in a well-publicized ratings war; but it has devastating human consequences as well.

The letter opens meanwhile with an overview of how difficult and painful the 1,644 days have been since these parents lost their children.

'Erica Lafferty walked through a graveyard in her wedding dress and veil so that she could feel close to her mother, Dawn Lafferty Hochsprung – a woman who died trying to protect other parents’ children.

'Then there are all the other days; regular Thursdays like this one where a sound or a smell can transform the unrelenting ache of grief into intense, physical pain.'

It is signed by Mark and Jacqueline Barden, Hannah D’Avino Nicole and Ian Hockley, Erica Lafferty, Veronique Pozner, Donna and Jillian Soto, Carlee Soto Parisi , and David and Francine Wheeler.

Kelly has kept relatively quiet about the controversy over her interview with Jones, which has been brewing since she previewed the pair's sit-down on the most recent episode of 'Sunday Night With Megyn Kelly.'

Kelly did briefly address the issue in an interview with The New York Times while defending her decision to bring Jones on her program.

'What we do as journalists is we shine a light on those with power, those with influence, those who have become culturally relevant,' said Kelly.

'Of course, it's upsetting to know that doing that causes any upset to the Newtown families, many of whom I know well. But I have to do my job.'

'As journalists, we don’t get to interview only the good guys — that’s not journalism,' Kelly told the Times.

'It’s going to be very difficult for us to keep an eye on the more controversial figures of our time if we never talk to them.'

Kelly said she sat down with Jones to examine 'his influence and his — for lack of a better term — method for putting information together to figure out how he got to be so important in the president’s world, in millions of people’s world.'

She also stated that currently 'there are a lot of people who are very angry that Donald Trump is president and a lot of people who believe Alex Jones played a large role in it.'

Kelly is also dealing with another issue as the second episode of her NBC news magazine tanked in the ratings, losing almost half its audience from the premiere one week prior.

Final Nielsen numbers show that the latest episode of 'Sunday Night With Megyn Kelly' pulled in 3.61 million total viewers and scored an 0.6 rating in the all-important adults 18-49 demo, which was a slight improvement in the 7pm time slot from the previous year.

It was far, far lower however than the 6.1 million viewers and 0.8 rating notched by the premiere, which featured an interview with Russian president Vladimir Putin.

Kelly has been feeling the heat over her decision to interview InfoWars' host Alex Jones for her Sunday news magazine this week.

Sandy Hook Promise, an organization that was created in memory of the 20 students and six staff members who were massacred in the 2012 school shooting in Newton, Connecticut, announced on Monday that Kelly would no longer host one of their annual Promise Champions Gala,

That announcement came just two days before Kelly was set to take the stage at the event on Wednesday night in Washington DC.

The decision made by the non-profit organization also left Kelly with a big gap in her episode that will be airing this Sunday, as she planned to film the gala to run alongside her interview with Jones.

That plan went up in smoke however when she managed to draw the ire of Sandy Hook parents, who lashed out loud and quick as they attacked Kelly for allowing Jones' ideas to be heard by her audience of 6 million.

Kelly responded to the controversy on Tuesday in a statement, saying she was 'disappointed' but also 'respected the decision' of the charity.

'I understand and respect the decision of the event organizers but I'm of course disappointed that I won't be there to support them on Wednesday night,' began Kelly in her statement.

'I find Alex Jones's suggestion that Sandy Hook was "a hoax" as personally revolting as every other rational person does.'

She then explained: 'It left me, and many other Americans, asking the very question that prompted this interview: how does Jones, who traffics in these outrageous conspiracy theories, have the respect of the president of the United States and a growing audience of millions?'

Kelly then offered theories, stating: 'President Trump, by praising and citing him, appearing on his show, and giving him White House press credentials, has helped elevate Jones, to the alarm of many.'

'Our goal in sitting down with him was to shine a light - as journalists are supposed to do - on this influential figure, and yes - to discuss the considerable falsehoods he has promoted with near impunity,' said Kelly.

Regardless of the aim, advertisers were not happy, and JP Morgan pulled their spots from the time slot.

In the preview of her interview with Jones, the NBC News host demands to know how he can declare something like Sandy Hook a hoax given the loss of young lives and parents who are still grieving for their children.

'Oh I know, but they don't get angry about the half-million dead Iraqis from the sanctions...' starts Jones before he is cut off by Kelly and accused of dodging her question.

'The media doesn't cover all the evil wars...' begins Jones, who again is cut-off by Kelly.

'That doesn't excuse the things you said about Newtown, you know that,' states the host, who actually traveled to Texas to meet with Jones in his own studio.

'Here's the difference, I looked at all the angles of Newtown and I made my statements before the media even picked it up.'

And in 2012, in the wake of the Aurora cinema massacre that saw 12 killed and 70 injured when a gunman opened fire during a screening of The Dark Knight, Jones claimed it was a 'false flag'.

'If you look at the full spectrum of information unfolding right now, 100 per cent chance that the mass murder committed in the suburb of Denver, Colorado, right next to Littleton and Columbine was a false flag mind control event.'

He even blamed President Obama for being behind a series of deadly tornadoes in Oklahoma back in 2013 that claimed the lives of over 30 people.
